Biomarkers of preclinical disease are critical for the development of disease\u2010modifying or even preventative therapies. Current biomarkers for early disease, including cerebrospinal fluid tau and amyloid \u03b2 (A\u03b2) levels, structural and functional magnetic resonance imaging, and the use of brain amyloid imaging, are limited because they are very invasive or expensive. Noninvasive biomarkers may be a more accessible alternative, but none can currently detect preclinical AD with the required sensitivity and specificity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Here, we show a novel, straight\u2010forward, and noninvasive approach for assessment of early stages of cognitive decline.

The accuracy for AD diagnosis shown by salivary lactoferrin was greater than that obtained from core cerebrospinal fluid (CSF) biomarkers, including total tau and CSF A\u03b2\n                      <jats:sub>42<\/jats:sub>\n                      .
